The thesis focuses on CKF to spread related research .

本文围绕CKF展开相关研究。

The maloperation of directional high frequency relay composed of CKF integrated circuit protective device and receiving transmitting unit is analyzed with examples .

对由CKF集成电路保护装置与收发信机构成的方向高频保护误动进行了具体的实例分析，找出了误动的原因是保护装置出口延时太短和收发信机存在收信间断问题。

The CKF-KF which performs a feedback correction to the linear state through the nonlinear state estimation error has higher precision than directly using CKF .

CKF-KF滤波过程中，通过用非线性状态的估计误差反馈修正线性状态的估计获得了比直接使用CKF具有更高的精度。

The 21-dimensional CKF brings the calculation burden on the computer and the difficulty to meet a high filtering updating rate desired by rapid TA .

用于快速传递对准的卡尔曼滤波器的阶数将高达21维，故需要进行大处理量的滤波计算，这将导致快速传递对准所要求的快速滤波更新率得不到满足。

The CKF and KF are matched together through successively conducting cubature-sample to nonlinear and linear state , and cubature-sample to linear state is the key to their combination .

通过先后对非线性状态及线性状态进行Cubature采样而将CKF与KF匹配在一起，对线性状态也进行Cubature采样是它们融合的关键。

A Crankshaft Fluctuation Sensor ( CKF ) is located near the bottom of the timing cover where it generates a signal as the crankshaft timing chain sprocket rotates past it .

曲轴位置传感器安装在定时器壳底部附近，产生一个曲轴定时链轮齿通过的信号。

Cubature Kalman filter ( CKF ) is a superior nonlinear filter that has a simple algorithm , high precision and good convergence , etc. And it is becoming a hot and efficient method to study the nonlinear estimation problems for the current and future .

Cubature卡尔曼滤波（CubatureKalmanFilter，CKF）是一种性能优越的非线性滤波，具有算法实现简单、滤波精度高、收敛性好等优点，正逐渐成为当前及未来研究非线性估计问题的热点和有效方法。
